I may have overloaded my brain this semester, after taking almost year off I dove right back in by taking the full credit max for the summer semester. So, in the fall I am opting for only 2 classes since I completely bombed the entire summer semester.

I don't know what it is but I will dive right into the material at the beginning of every semester and will even be interested in doing it. But, by the halfway point I dont know what happens I will lose the interest and can barely even force myself to do the work, what is up with this?
